The Sennheiser EW-D SK BASE SET (Q1) is a core digital wireless system package providing the essential electronic components for a bodypack-based wireless link, operating in the Q1 sub-band within the 470 to 526 MHz range. This set includes the EW-D SK digital bodypack transmitter and a compatible EW-D series single-channel rackmount receiver, but intentionally excludes a microphone. This configuration is designed for maximum flexibility, catering to professionals who already own or wish to select their own specialized lavalier, headset, or instrument microphone. It allows users to leverage the high-performance digital wireless platform while using their transducer of choice.

The system delivers the full capabilities of the EW-DX series: pristine 24-bit/48 kHz digital audio transmission, ultra-low latency, and secure 128-bit AES encryption. The receiver features Intelligent Antenna Diversity for robust RF performance. The bodypack transmitter includes an OLED display for clear status monitoring and is powered by two AA batteries. This base set is an ideal building block for system integrators, rental companies, and audio engineers who require the reliability and audio quality of Sennheiser's top-tier digital wireless technology but need the freedom to pair it with any compatible microphone for bespoke applications in broadcast, theater, or live sound.
